[issue26095] Update porting HOWTO to special-case Python 2 code, not Python 3

[Nick Coghlan]

Nick Coghlan added the comment:

The feature detection approach is especially important for anything covered by 
the security backports in PEP 466 and 476, but can also apply for things like 
installing the importlib2 meta_path hooks into Python 2.7.

[issue26089] Duplicated keyword in distutils metadata

[Ezio Melotti]

Ezio Melotti added the comment:

This seems to be because the alternative spelling "licence" was also included 
in the list, and got changed in #693470/178d19cff163.
Because of that change, the method get_licence() is not supported anymore, but 
at this point removing the duplicate "license" should be safe.
Attached a patch.
(Note that there seem to be no tests for the "licence" alias in 
Lib/distutils/tests)

I think this is not worth fixing, for two reasons:
1) we are moving away from Rietveld;
2) even if we document it, most people won't go looking for naming conventions

I'm therefore going to close this -- thanks anyway for the report.

[issue26090] More correct string truncating in PyUnicode_FromFormat()

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

The C code often uses %. in PyUnicode_FromFormat(). %.200s 
protects from unlimited output when broken pointer points on random 
non-null-terminated data. %.200R is used to limit the size of human-readable 
messages.

In all these case formatted string can look well-formed with short data, but 
mis-formed (not closed quote, truncated backslash escaping or � decoded from 
truncated UTF-8 sequence) with long data.

I propose to make truncating in PyUnicode_FromFormat() more smart.

1. Truncated %R should keep at least one end character (the quote or ">").
2. Truncated output should include "..." or "[...]" as truncating sign.
3. \c, \OOO, \xXX, \u, and \U should not be truncated. It is better 
to omit these sequences at all (cut the string before them) that output them 
truncated.
4. Doesn't truncate UTF-8 sequence inside a character for %s.

[issue25995] os.walk() consumes a lot of file descriptors

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

> But using FDs proportional to the tree depth seems reasonable to me.

This was the main reason for rejecting issue15200. May be we can allow this for 
globbing, but only explicitly enabled with special parameter or separate 
functions. The benefit for globbing is starting to yield results without 
internal caching. The benefit for os.walk() is smaller, because in any case it 
yields files and directories not one-by-one, but collected into lists.

> Is there a potential hybrid strategy, where for small directories we close
> the FD but for large directories we keep it open?

May be with more complicated code. I think this needs explicit close() method, 
so it can go only in 3.6. For now I think we have to commit one of my patches 
(the difference only stylistic).

This is a patch against the pythontestdotnet repository to change the

If I push this patch to the pythontest repository, will the server immediately

[issue26092] doctest should allow custom sys.displayhook

[Sergey B Kirpichev]

New submission from Sergey B Kirpichev:

The purpose of doctest's - verify interactive examples.  But if
your users will use custom displayhook all the time (consider, as
examples CAS like SymPy or https://github.com/skirpichev/omg/) - why
you must show them examples with the builtin's displayhook?

After https://bugs.python.org/issue8048, sys.displayhook can't be
customized for doctest.  I think, that decision was wrong and we
should have a better solution.

PS: In fact, right now this issue can be workarrounded if you instead
override sys.__displayhook__ before doctest call.  But I believe
this "solution" has own problems.

[issue25995] os.walk() consumes a lot of file descriptors

[Guido van Rossum]

Guido van Rossum added the comment:

I like them both, if I had to choose I'd pick patch 2.

But yes, we need to add a close() method to the scandir iterator object.

In the meantime, I am still worried about what would happen if somehow the loop 
got interrupted and the frame got kept alive and the iterator wasn't closed by 
its dealloc until much later.  This kind of thing was common in asyncio and we 
had to resort to similar tricks to break some cycles. Maybe you can add a 
try/finally that *deletes* scandir_it to force it to close itself (at least in 
CPython)? That can go into 3.5.

[issue22642] trace module: convert to argparse

[SilentGhost]

SilentGhost added the comment:

Here is the updated version of the patch that addresses Senthil's comments. 
Besides re-flowing code, I've also added enforcement of --summary switch and 
re-factored and expanded the test_failures. It probably would be good if 
someone could test this on a real-life code.

[issue26093] __qualname__ different when calling generator object w/ functions.partial

[Dino Viehland]

New submission from Dino Viehland:

import functools
def f():
def g():
yield 1
return g

functools.partial(f())().__qualname__ != f()().__qualname__

The qualified name gets passed in via the interpreter loop with 
_PyEval_EvalCodeWithName calling PyGen_NewWithQualName.  If a generator object 
gets called from C then the qualified name gets lost.

It seems like _PyEval_EvalCodeWithName shouldn't exist and the generator code 
object should be able to get back to its qualified name so subtle differences 
like this don't happen.

[issue24955] webbrowser broken on Mac OS X when using the BROWSER variable

[Simon Conseil]

Simon Conseil added the comment:

I have looked at the webbrowser tests and it seems not so easy: currently the 
MacOS browser classes are not tested, and they don't the GenericBrowser base 
class. Instead they use custom code with os.popen, so it would require some 
work either replace os.popen with subprocess.Popen, or to mock the os.popen 
calls. I'm not sure I will the time to dig into this.

[issue26090] More correct string truncating in PyUnicode_FromFormat()

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

I think we can make this feature available with classic formatting '%.100r', 
but with new formatting '{0:.100!r}' (especially with f-strings) this can be 
not so easy.

Simon, sure. It is just for someone, either commiters or other interested folks

[issue26094] ConfigParser.get() doc to be updated according to the configparser.py header doc

[khyox]

New submission from khyox:

For the sake of clarity, in 
https://docs.python.org/3.5/library/configparser.html#configparser.ConfigParser 
the ConfigParser.get() method doc could be properly updated with merging the 
information written in the header doc of the source file, as found in 
https://hg.python.org/cpython/file/3.5/Lib/configparser.py

Concretely, this sentence there, "Return a string value for the named option." 
could be considered quite relevant to be added to the doc of the method, as 
some packages are (incorrectly) expecting boolean values returned by the 
ConfigParser.get() method. The reality is that a "True" in the configuration 
file is returning the string "True" and not the boolean constant True.

To sum up, the suggested update would be:

def get(self, section, option, *, raw=False, vars=None, fallback=_UNSET):
"""Returns a string value for the named option for a given section.

If `vars' is provided, it must be a dictionary. The option is looked up
in `vars' (if provided), `section', and in `DEFAULTSECT' in that order.
If the key is not found and `fallback' is provided, it is used as
a fallback value. `None' can be provided as a `fallback' value.

If interpolation is enabled and the optional argument `raw' is False,
all interpolations are expanded in the return values.

Arguments `raw', `vars', and `fallback' are keyword only.

The section DEFAULT is special.
"""

[issue25924] investigate if getaddrinfo(3) on OSX is thread-safe

[A. Jesse Jiryu Davis]

A. Jesse Jiryu Davis added the comment:

NetBSD has a concurrency test for getaddrinfo, so I tried it on Mac to see if 
getaddrinfo is thread-safe here, too. It appears that it is thread-safe.

I copied NetBSD's getaddrinfo concurrency test "h_resolv.c" and the test's data 
file "d_mach" from src/tests/lib/libpthread in the NetBSD 7 source:

http://cvsweb.netbsd.org/bsdweb.cgi/src/tests/lib/libpthread/

I've also attached these files to this ticket.*

The test program h_resolv.c compiles fine on Mac OS X 10.10 with clang 7, and 
the test passes using the same parameters that the NetBSD test uses, resolving 
five host names on five threads:

./h_resolv -d -n 5 -h 5 d_mach

There's even evidence that getaddrinfo is actually concurrent on my Mac: 
resolving 100 hostnames on 1 thread takes about 6 seconds, but using 100 
threads take only 3 seconds. To test concurrency I ran this:

sudo dscacheutil -flushcache
sudo killall -HUP mDNSResponder
time h_resolv -d -h 100 -n 1 d_mach

sudo dscacheutil -flushcache
sudo killall -HUP mDNSResponder
time h_resolv -d -h 1 -n 100 d_mach

Those sudo commands flush the Mac's DNS cache between runs.

* I removed one unresolvable domain, "cnftp.bjpu.edu.cn", from the test file 
d_mach. That domain took 15 seconds to time out and made the rest of the timing 
irrelevant.

[issue26095] Update porting HOWTO to special-case Python 2 code, not Python 3

[Brett Cannon]

New submission from Brett Cannon:

As pointed out by 
http://astrofrog.github.io/blog/2016/01/12/stop-writing-python-4-incompatible-code/,
 special-casing Python 3 code instead of Python 2 code when writing Python 2/3 
code will lead to breakage when Python 3 comes out. There should probably be a 
note in the porting HOWTO mentioning that you should always special-case Python 
2 code and not Python 3 code.

[issue26096] '*' glob string matches dot files in pathlib

[JitterMan]

New submission from JitterMan:

Path('.').glob('*') generates all files and directories in '.' including hidden 
files (those that begin with '.'). This behavior is inconsistent with the shell 
and with the old glob module, which only generate hidden files if the glob 
pattern starts with a '.'.
